As of perl5.7.2 all tests pass under:
Watcom 10.6 with Beta/970211.wcc.update.tar.F
socket3r.lib Nov21 1996.
As of perl5.8.1 there is at least one test still failing.
Some tests may complain under known circumstances.
See below and hints/qnx.sh for more information.
Under QNX 6.2.0 there are still a few tests which fail. See below and
hints/qnx.sh for more information.
Required Software for Compiling Perl on QNX4
As with many unix ports, this one depends on a few "standard" unix
utilities which are not necessarily standard for QNX4.
This is used heavily by Configure and then by perl itself. QNX4's
version is fine, but Configure will choke on the 16-bit version, so
if you are running QNX 4.22, link /bin/sh to /bin32/ksh
ar This is the standard unix library builder. We use wlib. With
Watcom 10.6, when wlib is linked as "ar", it behaves like ar and
all is fine. Under 9.5, a cover is required. One is included in
nm This is used (optionally) by configure to list the contents of
libraries. I will generate a cover function on the fly in the UU
cpp Configure and perl need a way to invoke a C preprocessor. I have
created a simple cover for cc which does the right thing. Without
this, Configure will create its own wrapper which works, but it
doesn't handle some of the command line arguments that perl will
throw at it.
You really need GNU make to compile this. GNU make ships by default
with QNX 4.23, but you can get it from quics for earlier versions.
Outstanding Issues with Perl on QNX4
There is no support for dynamically linked libraries in QNX4.
If you wish to compile with the Socket extension, you need to have the
TCP/IP toolkit, and you need to make sure that -lsocket locates the
correct copy of socket3r.lib. Beware that the Watcom compiler ships
with a stub version of socket3r.lib which has very little
functionality. Also beware the order in which wlink searches
directories for libraries. You may have /usr/lib/socket3r.lib pointing
test is triggered because cwd calls `fullpath -t`.
ext/IO/lib/IO/t/io_sock.t: Subtests 14 and 22 are skipped due to the
fact that the functionality to read back the non-blocking status of a
socket is not implemented in QNX's TCP/IP. This has been reported to
QNX and it may work with later versions of TCP/IP.
t/io/tell.t: Subtest 27 is failing. We are still investigating.
QNX auxiliary files
The files in the "qnx" directory are:
A script that emulates the standard unix archive (aka library)
utility. Under Watcom 10.6, ar is linked to wlib and provides the
expected interface. With Watcom 9.5, a cover function is required.
This one is fairly crude but has proved adequate for compiling
A script that provides C preprocessing functionality. Configure
can generate a similar cover, but it doesn't handle all the
command-line options that perl throws at it. This might be
reasonably placed in /usr/local/bin.
Outstanding issues with perl under QNX6
The following tests are still failing for Perl 5.8.1 under QNX 6.2.0:
op/sprintf.........................FAILED at test 91
lib/Benchmark......................FAILED at test 26
This is due to a bug in the C library's printf routine. printf("'%e'",
0. ) produces '0.000000e+0', but ANSI requires '0.000000e+00'. QNX has
acknowledged the bug.
